To aZZ whom it may concern Be it known that we, HERBERT WV. SAUBER and NORMAN B. PAULSON, citizens of the United States, residing, respectively, at Le mont, Cook county, Illinois, and Lockport, lVill county, Illinois, have invented certain new and useful Improvements in Methods of Constructing Reinforced Concrete Structures, of which the following is a specification, reference being had therein to the accompanying drawings.

Our invention relates to a new and improved method of constructing reinforced concrete structures, such as walls and partitions for buildings, and consists in the matters hereinafter described and then pointed out in the appended claim.

In the accompanying drawings we illustrate the several steps involved in carrying out our invention, and in these drawings Figure 1 is a perspective view of a side elevation of parts of a section of a wall illustrating the initial steps of our process; Fig. 2 is a detail side view showing two of the uprights or columns and filler slabs in place therein; Figs. 3 and 4 are detail views showing two of the uprights in horizontal section and the filler slabs in top plan view; Fig. 5 is a sectional view of one of the slabs and showing the arrangement of parts for an air space, and Fig. 6 is a perspective view on an enlarged scale illustrating the final steps for the initial panels and also the steps when upper panels or wall sections are in process of construction.

In practising our invention we first provide a suitable base or foundation A, preferably of cementitious material, and form thereon at suitable distances apart in suitable molds or forms (not shown) a plurality of concrete uprights or columns B which are made in plastic condition and allowed to set. The uprights may have any suitable form of reinforcing means, such as the rods 7), embedded or secured therein, these columns or uprights at this stage of the process being carried to a predetermined height such as the first level or floor of the finished building or structure, as shown in Fig. 1. The columns are begun by embedding their rods or bars I) in the material of the foundation, and these bars may extend to the height of the completed structure or may be individual for each rise or panel, as may be preferred, and the cementitious material for each column is put into its form or mold (not shown) in plastic condition so that as the lower portions set it unites with the material of the base to form a homogeneous structure. hen the columns are formed they are provided on their sides with longitudinal channels or ways 5 which in each panel form an opposite pair as clearly shown in Figs. 3 and l.

The filler slabs C are preferably constructed of molded material set or hardened before being placed in position in the wall or partition and are made of sutiicient length to have their ends enter, more or less, the opposite ways 7) of a pair of adjacent uprights, and are preferably formed of reinforced concrete with corresponding tongues c and grooves c on their opposite edges. When the uprights are completed to a predetermined height or level the slabs are putin place, and this may be done in different ways. Each slab may be raised by a derrick to position to have its ends enter the open ends of the channels or ways in its associated pair of uprights and when properly centered in position with respect to the associated ways it is lowered into place therein, and this operation is repeated with a sufficient number of slabs to fill each panel between each pair of uprights to a height at least flush with the temporary height of the uprights, and the slabs then stand as shown in Fig. 3; or each slab may be formed of a length appreciably less than the distance between the bottom of one of its channels and the opposite face of the other upright, and one end of the slab may be entered in one of the channels to a depth sufficient to allow its other end to clear the opposite upright when the free end may be swung into position in line with the channel in that upright and the slab then crowded or pushed to position in the channel thereof, and his operation is repeated with a sufficient number of slabs to fill each panel between each pair of uprights to a height at least flush with the temporary height of the uprights,-

and the slabs then stand substantially as shown in Fig. 4. In either case the spaces between the ends of the slabs and the bottoms of the grooves may be filled with plastic concrete, as shown at b in Figs. 3 and 4. When the slabs of one or more panels of a level or particular elevation, as for example in Fig. 1, are in place a cross-beam or girder D of plastic concrete is formed in a suitable mold or box (not shown) extending across the adjacent uprights of the filled panel or panels as shown in Fig. 6 and binding the uprights and slabs in position, the girder preferably being provided with any suitable reinforcing means such as the rods Or bars cl which may extend the full length of the girder across all the uprights of an associated row or level or may be sectional, as desired. The slabs of the panels may be quickly assembled in place so that the plastic material for the crossbeam or girder may be positioned to set with the final setting of the material of its uprights, and as the material of the crossbeam interlocks with the upper tongue 0 of the upper slab of its panel or panels these parts unite as a homogeneous mass and as the upper face of the base is preferably provided with a tongue a to enter the groove of the lowest slab in each panel and as all the tongues and grooves are grouted with fresh concrete and the spaces at the ends of the panels are filled with similar material it is obvious that with the setting of all this material all the parts are homogeneously united. After the cross-beam or girder of the first level is formed, the uprights B for the next succeeding level are formed as before, the filler slabs C are assembled, and the next cross-beam D is formed, this being illustrated in Fig. 6 which shows the uprights B and also the slabs C of one panel of the second level completed with intermediate window construction and one of the slabs C of a second panel in place, with the reinforcing rods cl in place ready for the cementitious material of the next crossbeam or girder D and part of the latter formed. Only one slab C is shown in the right hand panel of Fig. 6 in order to show the channels in the uprights and this slab is shown as broken away to show the construction providing an air space for the wall or partition by means of the Z-shaped pieces e having one wing molded into the material of the slabs and whose other wings form means for attaching the expanded metal sheets 6' for the inside plaster finish. Ad-

ditional levels for succeeding upper floors or projections may be added, and in such case the cross-beam of each lower panel forms the base of the next upper level and the lower portions of the columns and the lower slab of the next level may be formed and placed in position before the material of the cross-beam sets so that these parts finally form a homogeneous mass. Furthermore, by our process all the parts of each panel and all the panels of a wall or partition are bonded together; the rods 6 extend into the base and above the upper ends of their uprights so that the material of the cross-beam or girder sets about them and so whether the rods extend the full height of the several levels or are merely of sectional lengths sufficient to enter the respective longitudinal members provided by the base and cross-beams the longitudinal and upright members together with the filler slabs are securely bonded.

We claim The method of constructing reinforced concrete structures which consists in forming a cementitious longitudinal member; embedding therein the ends of upright reinforcing rods; forming on said member and about said rods to predetermined height less than the length of the rods a series of spaced concrete uprights or columns having opposite longitudinal channels or ways; filling the spaces between adjacent columns with sectional concrete slabs with their ends in the ways; and forming a reinforced concrete cross-beam or girder across the adjacent col umns and about projecting portions of said rods.

In testimony whereof we afiix our signatures in presence of two witnesses.
